    • Natural selection
    • - Since individuals that survive to reproductiveage are generally viewed as being physically fitter than those which
  23. A woman conceives 3 children during her lifetime. What is her fitness?

    the result that they are more likely to become established in the culture. 
    What is the term for this?
    Gene-Culture Co-Evolution
  50. Define Epigenesis
    • The interaction between genes and the environment that occurs during
    • development. Epigenetic rules embody certain biological imperatives, and these
    • rules influence the set of cultural entities that are likely to exist. Because
    • these rules are shaped by genes, Lumsden and Wilson suggest that genes
    • indirectly influence culture.
  51. Why do Lumsden and Wilson suggest that genes indirectly influence culture?
    Because the RULES that make up culture are INFLUENCED BY GENES.
  52. Patterns of cultures that are transmitted
    between individual. These serve to increase the inclusive fitness of those
    humans who acquire the particular aspects of a culture. Examle: Food
    consumption and taboos

    What are these 2, and what is the theory called?
    • Culture, Genes
    • "Dual Inheritance and the Evolution of Culture"
  55. Brains are costly in a biological sense (e.g. metabolically), but they make up for their existence because ___ is slow and brains are needed for the foundation of ___?
    • Because environment changes slowly.
    • Our brains are needed as they are the foundations for culture (The Transfer of knowledge)
  56. imitation, modeling and idea diffusion are examples of what kind of Culture, according to Tooby and Cosmides?
    Transmitted culture (in our minds, not innate)
  57. TOOBY & COSMIDES coined the term ________ to describe how cultural practices might arise as a result of mental modules that are environmentally contingent.
    EVOKED culture
  58. This type of knowledge and interpretations are those existing within a culture, that are ‘determined by local custom, meaning, and belief’ and best described by a 'native' of the culture. These are social constructivists, open-ended, prone-to-bias, "The _____ approach investigates how local people think" How they perceive and categorize the world, their rules for behavior, what has meaning for them, and how they imagine and explain things. It is frequently used by Anthropologists. 
  59. "The _______ (scientist-oriented) knowledge approach shifts the focus from local observations, categories, explanations, and interpretations to those of the anthropologist. The ______ approach realizes that members of a culture often are too involved in what they are doing to interpret their cultures impartially. 
  60. Donald Brown was an Anthropologist who noted what in regards to ... What?
    That there seem to be Universials of Culture, e.g. burial, gender roles, incest taboos. 
  61. How did FRANK BOAS explain behaviour in relation to culture?
    This is also known as the _______ theory of culture.
    • There is no specific psychological difference between people, but rather, culture is needed to understand the variation in behaviour.

    Image Upload
  63. Evolutionary theory usually use ______ explanations in regards to culture. 
    This is because Culture is thought to have increased our______
    Usually use ultimate levels of explanations; There is evidence that a certain type of brain is required for culture. This is because Culture is thought to have been advantageous for us in terms of INCLUSIVE FITNESS
  64. How large is the proportion of intelligence and thought to be accounted for by heritability?
    Image Upload
    0.5, or 50% determined by genes.
  65. Evolutionary psychologists suggest that culture is partly cause of our genetics, however, there seems to be a great variability among cultures. How could this be explained as advantageous? 
    Image Upload
    Variability is essentially adaptability to the environment, which is essential if  the environment changes fast. 
  66. Why is it that there is no optimal human, and that individual differences are not necessarily selected against, with regards to ecology and culture?
    Culture and variability has helped us survive in many different ecological environments, thus, there may not be an optimal human; it depends on the place you grow up.

    Environment and the behaviour of others
  70. Serial killers or psychopathy could be due to Epiphenomenon. Explain
    Epiphenomenon is "a secondary phenomenon that occurs alongside or in parallel to a primary phenomenon", in this example, it could be sexual combination and mutation that may aid the creation of such apparently detrimental characteristics 
  71. The non Heritable Component

    Image Upload
    Social dimension
  75. Why is intelligence today not necessarily useful during the EEA
    • Today the focus is on math, general knowledge, language etc.
    • During EEA it was more about survival.
    • Intelligence is contingent on culture and environment

    Image Upload
    "A visionary leadership"
  83. Paranoia is subject to normal distribution
  84. There is evidence that Social competition can lead to what mental disorder in animals?
  85. Because there is always a normal distribution of genes, what does this tell us about psychopathology?
    There is always a normal distribution of genes so there are always mutations
  86. What does evolutionary psychology say about pathology in general?
    Symptoms may be adaptive and could increase inclusive fitness as it may protect us and compromise rather than only destroy us. They could also have been created due to novel environment
  87. With regards to emotions, why do people seek out short cuts that does not provide a long-term actual beneficial result?
    Because people seek positive emotional outcomes; people are guided by their emotions
  88. Alexythimia
    Image Upload
    Personality construct characterized by the sub-clinical inability to identify and describe emotions in the self.[1] The core characteristics of alexithymia are marked dysfunction in emotional awareness, social attachment, and interpersonal relating.[2] Furthermore, individuals suffering from alexithymia also have difficulty in distinguishing and appreciating the emotions of others, which is thought to lead to unempathic and ineffective emotional responding
  89. Difference between Alexythimia and Psychopathology?
    Theory of mind in regards to emotions is affected in psychopathology whereas in Alexythimia people are not "aware" of their own emotions.
  90. Emotions involve 3 parts, which?
    Physiological, Cognitive and Behavioural reactions to external and internal events

  95. Except for the brain, which 2 systems affect emotions (and essentially everything else in humans?)
    Endocrine system and Nervous system (Neurotransmitters)
  96. Why are NEGATIVE EMOTIONS "stronger" (i.e. under more evolutionary pressure) than Positive emotions ?
    They guide us away from threats, aversive situations. There might not have been a second chance
  97. Negative emotions usually affect a person's focus how?
    Narrowing the focus, so not that easily distracted from other things
  98. Positive emotions promote knowledge in 2 ways? 
    Image Upload
    Through Playfulness and Interest (emotion)
  99. Positive emotions are more differentiated than Negative emotions, and they narrow people's focus (enhance focus).
    FALSE. They are Less differentiated than negative emotions and tend to widen people's attention "Playfulness" rather than "Threat"
